The rail portion of this trip is a very popular one, with many trains running the route at the same time. Be sure and sit on the left hand side, as this is where the majority of the stunning views will be located.
Then it was back to Skagway, where there are plenty of shops that look identical to shops in other Alaskan ports and pretty much full of disappointing Made in China items. If you look carefully, authentic items can be found, but expect to pay for authenticity. If you like salmon you'll find everything that could possible be made of salmon ready to buy.
